DEVICE FOR"DRAW|NG OUT SPOKES FROM WHEEL-HUBS.

SPECIFICATION forming part of Letters Patent No. 288,511, dated November 13, 1883.

I Application filed September 1, 1883. (No model.)

To all whom itm/ay concern:

Be it known that 1, DAVID S. TALLMAN, a citizen of the United States, residing at Reno, VVashoe county, State of Nevada, have invented a new and Improved Device for Drawing Out Spokes from Carriage and Wagon Wheel Hubs, of which the following is a specification.

My invention relates to a tool which will be useful to carriage and wagon repairers in removing damaged, new, or broken spokes from wheel-hubs; and it consists in a combination of a clamping device, which is secured on the spoke to be withdrawn, and a vertical lever and horizontal push-bar, so arranged and j ointed together as to be operated to push the hub from off the spoke, as hereinafter described,

will have, say, three sizes of the tool, to suit when the spoke is inserted between.

small, medium, and large sized wheels. The two jaws are connected together just above the spoke by the straight key B, run through a slotted hole in each jaw, which key has a double head on one end, at b, and a slotted hole on the other end, just outside the clampjaw. A taper key, 0, drives through this slot and draws. the two jaws of the clamp together At E there is a fulcrum-pin to support the drawlever F. At the lower end of this draw-lever there is secured by a hinge-joint a push-bar, G, which has an end so shaped as to encircle nearly one-third of the hub, and, if necessary, a piece of leather, rubber, or other soft when a heavy pressure is brought against it. Also, a similar provision may be made for avoiding injury to the spoke, as well as to give abetter frictional hold for the clamp. (See Fig. 2, where I show the protecting strips I.)

In drawing the two clamp-jaws together by driving the key C they would bind on the draw'lever F and prevent its free action, if it were not for the separating screw-bolt J, which 5 5 has an adjusting-nut, K, upon it, so that the jaws A A cannot be drawn together farther than this nut will allow. By adjusting this nut the clamp may be also accommodated to the various thicknesses of spokes. The lever F need not be a long lever, but may be, as shown, simply a socket, into which a wooden or iron bar is inserted when the device is used.

The operation'is simple and as follows: The wheel is placed on the flat and firmly held in any suitable way. My clamp is then placed upon the spoke to be drawn at a point close up to the hub. The clamp is then drawn tightlyby driving the taper key 0. The lever F is then drawn back, the push-bar goes 7o forward to impinge against the hub, and with little efi'ort the spoke is drawn out. A Screw bolt and nut may be used instead of the keys B and C; but I prefer the keys. The inside of the clamp, where itinclasps the spoke, may 7 5 be roughened by grooves cut in their face, or in any other way, so as to prevent slipping.

What I claim as my invention, and desire to secure by Letters Patent, is as follows:

A spoke-extractor consisting of a combination of a clamp having jaws A A and suitable means to draw them together to tightly grasp the spoke, a Vertical draw-lever, F, with its fulcrum at E on the clamp, above the push bar G, and the push'bar G, attached to the lower end of the draw-lever below the fulcrum, substantially as and for the purpose de scribed.
